Thunderbolt 3.The most powerful and versatile port ever.

Thunderbolt 3 offers a connection with state-of-the-art speed and versatility. Delivering twice the bandwidth of Thunderbolt 2, it consolidates data transfer, video output and charging into a single compact connector. And with the integration of USB-C, convenience is added to the speed of Thunderbolt to create a truly universal port.

Blackmagic eGPU and eGPU Pro. More power to every pixel.

Blackmagic Design has created two external GPUs (eGPUs) ideal for your Thunderbolt 3–enabled Mac.2 So you can have desktop-class graphics performance without giving up the portability of a notebook. Housed in an all-in-one aluminum enclosure, Blackmagic eGPUs are powerful yet quiet, charge your Mac using Thunderbolt 3, and have built-in I/O connections to drive both a Thunderbolt 3 display and VR accessories simultaneously. Choose the Blackmagic eGPU to accelerate pro apps and enjoy supersmooth gaming, or the Blackmagic eGPU Pro for the ultimate workstation-class graphics performance for your pro app workflows and VR content creation.

Blazing-fast data transfer. Now even faster.

Transferring data at speeds of up to 40Gb/s, which is two times faster than Thunderbolt 2 and eight times faster than USB 3, Thunderbolt 3 delivers the fastest connection to any dock, display or device. You can also daisy-chain up to six Thunderbolt devices through a single port without needing a hub or a switch. So connecting a storage device to your computer, and then a display to your storage device, works as it’s meant to — with powerful throughput.8

More power to you. And all your devices.

With Thunderbolt 3, a single USB-C port can deliver power in both directions. So a port can charge a device or, alternatively, be charged by one. And it’s capable of delivering up to 100 watts of power, so a single cable can be used to connect to a dock or display and charge your MacBook Pro or MacBook Air simultaneously.
